Semantic Label Generation for Location Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Providing a clear location identifier in scenarios where physical addresses are insufficient, such as ride-sharing situations, especially in areas without street addresses or where geographic coordinates are not precise, leading to confusion between drivers and riders.
Innovation Solution
A system that determines a landmark or point of interest by analyzing geographic coordinates to generate a semantic label, including the street, segment, heading, and side of the street, and selects a nearby place based on popularity, visibility, and distance to provide a clear location orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If geographic coordinates are used for location identification, then location precision is improved, but usability and clarity are worsened because users cannot easily interpret coordinates without translation to addresses
Solution Approach 1:
The patent introduces geographic coordinates as an intermediary representation that bridges the gap between physical locations and semantic place names. Instead of directly mapping to addresses, the system uses coordinates as a mediator to enable precise location identification while maintaining usability through semantic labels derived from the coordinates
Solution Approach 2:
The system creates a virtual copy of the physical location in the form of geographic coordinates (latitude and longitude). This coordinate copy preserves the exact position information while allowing flexible processing and translation into various usable formats such as place names or descriptive labels
2Ease of operation
If physical addresses are used for location identification, then usability is improved, but reliability is worsened in areas without street addresses or where addresses span large areas
Solution Approach 1:
The patent changes the parameter system from address-based identification to coordinate-based identification. By using latitude and longitude as fundamental parameters, the system achieves reliable location identification independent of address system completeness, while coordinates can be translated back to usable place descriptions
3Loss of information
If semantic labels are generated from geographic coordinates, then location clarity is improved, but system complexity increases due to multiple processing steps
Solution Approach 1:
The system performs preliminary actions by pre-establishing the geographic coordinate framework and pre-processing coordinate-to-place translations. By having the coordinate system and translation mechanisms ready in advance, the system can quickly generate clear location descriptions without complex real-time processing when needed

AI summary
Systems and methods are provided for determining a street and segment corresponding to the geographic coordinates for a location and determining a heading and a side of the street for the location. The system and methods further provide for generating a list of places within a predetermined distance from the location, determining a first subset of places of the list of places that are located on the same street as the street corresponding to the geographic coordinates for the location, and generating a second subset of places from the first subset of places, each place of the second subset of places having a same heading and side of the street as the heading and side of the street for the location. The systems and methods further provide for selecting a place of the second subset of places and generating a semantic label for the selected place.
